Specification of Letters Patent.

Patented Aug. 2, 1910.

Application filed September 14, 1909. Serial No. 517,594.

To all whom itmag/ concern.

.lle it known that I, ROBERT R. S'rnrN, a cltizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Roundabouts, ot which the following is a specification. This invention relates to a roundabout inl which the principle of the aeroplane is taken advantage of. Broadly the device consists of a carriage or carriages equipped with a lifting plane in combination with a meansI for moving the carriages over a track or around a circle while still allowing them to soar aloft under the action of the planes. Y 4.

The device is capable of many forms but I prefer the one shown in the drawings as it is simple and eflicient. In this form a frame Work is mounted so that it may be loeated about a vertical axis, this trameY Werk carrying approximately vertical columns at lts outer perlphery. The carriages are mounted on these columps so as to slide vertically thereon and the linear velocity of the carriages and the inclination of the lifting planes are so arranged that -the carriages will be raised up the columns when the Whole frame is revolved. It will be seen that it is possible to mount the columns on any sort of structure which may be moved-such as a car running on a track."

This construction may be of great utility in some special cases, but fory general use I prefer the form shown in the accompanying drawings, in which, l

Figure 1 ,is a plan View of the `device. Fig. 2 is a side elevation of the same with parts broken away.

In the drawings 5 designates a revolving frame centered on a vertical axis 6 and composed of upper and lower frames 7 and 8 which are connected through the medium of columns 9. Thesecolumns are preferably square so that sleeves 10 fitted thereon cannot turn out of position. The columns are preferably arranged to project upwardly and outwardly, as shown in the drawings. Sleeves 10 each carry a car 11 havingseats 12 therein, for the accommodation of passengers. Mounted on the sleeves and beneath the cars are lifting planes 13 pivoted on shafts 14 and adjustable by means of gearing 15 which con nects the shafts With a steering wheel 16 located at a convenient point for the manipulation of the car. By means of this wheel the plane may be adjusted to any desired angle so that the height to which the car will rise is under control.

Bottom frame 8 is provided with rollers 2() which travel over a track 2l and aii'ord a solid and stable support for the. frame 5. Shaft 6 is rotated through the means of gearing 22, or any other approved means of power transmission, a step bearing 23 being provided for the shaft below the gear.

The Whole structure is rotated in the direction indicated by the arrows at an appropriate speed. The occupants of a car porting the car so that 'the ear will be moved upwardly by the pressure on the under side of the planes. When the desired height is reached thekinclination of the planes may be altered so that the car will remain at that height. When it is desired'to descend the inclination of the planes is again altered and the car Will move down the column alighting on a sprin 24 placed at the botttoni of the column as a .precautionary measure. Y

It will be seen that this invention consists broadly of a vertically extending column capable of being moved and having a car provided with a lifting plane slidably mounted on it. The minor details may be varied to suit individual tastes. In the pres- Ment showing the columns are sloped up- Wardly and outwardly so that' centrifugal force will aid in moving the carupwardly. This feature, of course, could not loe embodied in a device Where the column is moved in a straight line but only in the present casewhere the column isrevolved about a vertical axis.

Having described my invention, lA claim 1. A roundabout, -comprising a moving frame, a vertically extending column on the frame, a car adapt to slide up anddown the column, and a lifting plane mounted on the car. l

2. A. roundabout,l comprising aA rotating frame, a vertically extending column on the frame, a car adapted to slide up and down the column, and an adjustable lifting plane thereon, aud lifting mounted on the cars.

4. A roundabout, comprising a frame adapted to rotate about a vertical axis, a plurality of vertically and outwardly extending columns on the frame, and a ear mounted on each column and adapted to slide thereon.

5. A roundabout, comprising a movable frame, avertical member on the frame, a car adapted to slide up and down the vertical member, and means mounted on the car for lifting it by reaction upon the atmosphere.

6. A roundabout, Comprising a rotating frame, an approximately vertical member planes adjustably eeeaee on the 'ran'ie, a ear adapted to slide up and. down the rne1nber,' and means mounted on the car for lifting it by reaction upon the atmosphere.

7. A roundabout, comprising a rotating Jframe, a vertically extending member 'mounted on the frame, a ear mounted on the member to slide thereon, and-means on the ear to raise it by reaotion ou the atmosphere. In Witness that l claim the 'foregoing have hereunto subscribed my name this 8th day of September', 1909.
